Bottled water manufacturers’ encourage the perception that their products are purer and safer than tap water. Bottled water can cost up to 10,000 times more per gallon than tap water. But the reality is that tap water is actually held to more stringent quality standards than bottled water, and some brands of bottled water are just tap water in disguise. What’s more, our increasing consumption of bottled water—more than 22 gallons per U.S. citizen in 2004 according to the Earth Policy Institute—fuels an unsustainable industry that takes a heavy toll on. Approximately 1.5 million barrels of oil—enough to run 100,000 cars for a whole year—are used to make plastic water bottles, while transporting these bottles burns even more oil.
